Non-merged Data Summary
Overall, average symptom severity decreases with consecutive testing. Also, the average symptom severity score is lower for individuals who complete one post-injury test that individuals who complete multiple post-injury tests, suggesting symptom severity on the first post-injury test is predictive of requiring multiple post-injury tests.
